What It Is and How It Works
Ivermectin is an antiparasitic medication primarily used to target parasitic worms. It works by binding to parts of parasite cells, increasing the permeability of cell membranes to chloride ions. This results in paralysis and death of the parasite, effectively clearing the infection.
Indications / Uses
In humans, ivermectin is FDA-approved for the treatment of onchocerciasis (river blindness) and strongyloidiasis, which are parasitic infections. Its role in veterinary medicine includes treatment for various internal and external parasites in animals. There has been interest in its off-label use for other conditions, though such uses require clinical supervision and more supporting evidence.
Dosage Forms and Typical Dosing Considerations
Ivermectin is primarily available as oral tablets for human use. Topical formulations exist for veterinary uses. When prescribed, dosing depends on the specific condition being treated, patient weight, age, and other health considerations. It is crucial to follow the approved dosing regimen provided by a healthcare professional.
How to Take It Correctly Step-by-Step
Oral ivermectin should be taken with a full glass of water on an empty stomach, preferably an hour before breakfast. If a dose is missed, take it as soon as remembered, unless it is near the time for the next dose. Do not double doses. Store in a cool, dry place away from sunlight. Avoid alcohol consumption while on ivermectin treatment.
